i have on .iso file of an operating system. i have done this is the past with linux and nero and i never had any boot issues. however, since the file is more then 2 gig's, nero wont let me make a bootable dvd. i have magic iso and i cant figure it out. when the file burns, it wont let it load from dos, and my dvd drive is set to boot from my cd/dvd drive first and then my hard drive. however, once windows loads up, i can run the install from windows. i want to do a clean install though. if anyone can help me on this that would be great.
